Specification of Letters .Patenti Application filed April 5, 1912, Serial No. 688,750. Renewed March 12, 1914. Serial No. 824,315.

citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Adjustable Swinging Window-Sashes, of which the following 1s a specification, reference being had to the'accompanying drawings.

'lhis-iurention relates to improvements 1n windows and has for its object'to provide a window embodying vertically movable sashes mounted in the window frame for swinging movement, and means for securlng said sashes in their open position at any point in the frame.

Another object of the invention is to provide swinging window sashes having stiles and supplemental stiles pivotally connected at their lower ends. and means for mounting said supplemental stiles whereby a practicallv air tight joint is formed between the same and the stiles of the sashes when said sashes are losed.

Another and more specific object of the invention resides in the provision of verticallv sliding supplementa stiles mounted in the window frame and the sashes pivotally mounted upon the lower ends of said stiles, said sashes having swinging movement through an arc of substantially ninety degrees, and means carried by the sashes operating with means mounted upon the supplemental stiles to engage the window frame and securely hold the stiles against further slidim movement.

Another ob ect of the invention is to provide a device of the above character wiich consists of comparatively low elements which may he nnmnfactnred and installed at a comparatively small cost and produce a device which is reliable in operation.

With the above and other objects in view, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter more fully describe and claim.

For a full understanding of the invention.

reference is to ho had to the following description and accompanying drawings in which Figural is a front elevation oi a window partly in section oonstrnctml in accordance with the present invention; Fig. 2 is a ilOIlzon'tal section taken on the-lino 2-4.2 of Fig.

the window sashes.

1; Fig. 3 is a perspective view showing one of the sashes in its open position; Fi 4 is a section taken on the line Lt-4 of l ig. 1; Fig. 5 is an enlarged section illustratin the sash'lock in detail; Fig. 6 is a detail ingmentary perspective view of the supplemental stile; F i 7 is a pore )ective view of the late secure to the win ow stile which carries the stop lag; and Fig. 8 is a detail section of the supp cmental stile illustrating on an enlarged scale the form of guide eyelet for the sash cord which is carried by said stile.

Corresponding and like parts are referred to in the following description and designated in all the views of the-accompanying drawings by the same reference numerals.

Referring in detail to the drawings 5 designates generally the window frame which is of the usual construction and is provided with the weight chambers (3 separated by the vertical partition member 7. The inner wall 8 of the window frame at each side thereof is mortised as at 9 to receive a parting bead 10 which separates the two sashes of the window for vertical movement in spaced grooves or channels. The rear wall 11 of the frame is extended inwardly beyond the side wall 8 thereof and forms a stop for one of the sashes, a stop strip 12 being secured to the inner wall of the frame adjacent to its inner edge to provide a stop or holding strip for the other of As the manner oi mountin the two sashes in the window frame is identical the detailed descri tion of one of such mountings will sullice or both of the sashes.

In the sash receiving grooves of the window frame the supplemental stiles indicated generall by the numeral 13 are slidably mounte These supplemental stiles differ slightly in roportion for the upper and lower sashes at are each of channel form in cross section, as clearly shown in Fig. 2. The edge of one of the side walls of the stile is outwardl flanged as indicated at 14 and loosely fits into a longitudinal kerf 16 formed in the head 10 and the outer wall 11 respectively of the frame. This flanged wall oi. the supplemental stile is also rovided with an extension 16 which projects laterally from the face of the intermediate portion of the stile and extends the entire length thereof. The window-sash 17 has a plate 18 ill) ill)

lili) llO countersunk in the face of the sash stile and securely fixed thereto by means of suitable screws. The body wall of the supplemental movement in an arcuate slot 21 formed in the lower end of the supplemental stile 13. This lug engaging the opposite end walls of said slot limits the swinging movement of the window sash upon the lower end of the supplemental stile so that the sash is movable from a vertical to a horiz0ntal position or through an arc of substantially ninety degrees.

The window sash is normally held in its closed osition by means of the usual eounter alancing weight 22 which is secured to one end of the sash cord 23, said cord passing over the usual guide pulley or sheave (not shown) at the top of the window frame, and then extendin downwardly between the parallel walls 0 the supplemental stile 13. This-sash cord-extends through a guide eye 24- secured in an opening rovided ably fixed to the sash stile as shown. at 25. It will be observed that the guide eye 24-is provided with a rounding convex projecting portion which extends outwardly into the channel of the stile 13, thereby providing a smooth surface over which the sash cord moves and eliminates all liability .of said cord being cut in the swinging movement of the sash. The secured edge of the guide eye i disposed in a counter-sink or recess provided in the outer face of the supplemental stile 13. v

In order to hold the supplemental stile 13 against further vertical movement afterthe window sash has been'moved in the frame in position to be opened or swun out of the ame in order to secure the desired amount of ventilation, I employ the stop device shown in Fig. 4 which consists of a spring plate 26 rigidly fixed at one of its ends toone of the parallel walls of the supplemental stile 13. This spring plate extends from itsinal position, or entirely closed within the window frame, this lug engaging the depending flange 28 of the plate 26 forces said plate inwardly to dispose the holding block 29 out of engagement with the frame of the window. This sash holding block is movable through a rectangular-opening 30 in the front wall of the stile 13 and is provided witha serrated or roughened face 29 for gripping engagement with the stop strip 12 or the bead 10, as the case may be. By

means of this construction it will be readily seen that as soon as the sash has been moved to the desired position in the window frame and said sash swung out of said frame to its open position, the stop lug 20 is disengaged from the lower end of thespring plate 26, thereby permitting said plate to assume its normal condition and project the stop block 29 through the opening 30 of the stile 13 and into engagement with the window frame, thereby holding the stile 13 against further sliding movement and supporting the sash in the position to which it has been adjusted in the frame of the window.

In addition to the foregoing features of construction, I also provide a holding device which is mounted upon the upper end of the supplemental stile 13 whereby the sash may be-securely held in its closed position in the frame of the window. This sash lock includes a spring late 32 fixed at one end to the body" wall 0 the supplemental stile and provided at its other end with a cylindrical conical shaped stud 33 which is loosely disin the body wall of the stile 13 an is s'uitp osed through an opening in the stile and 1s adapted to be received in a central opening 35 provided in the plate 34 which is fixed to the stile of the window sash. The

plate 32 has 'an opening 36 therein adjacent stile, and place the spring plate 32 under tension. Thus, when the sash is entirely disposed within the window frame and the stud 33 is opposlte the opening '35 of the plate 34:,

- the spring plate 32 in assuming its normal position projects the stud 33 into said openin whereby the window sash is securely he d in the frame against casual swinging movement.

-. A before stated, thechanneled stile'13 is rovided with a flange 14 for engagement in a groove of the window frame and for the purpose of effecting an'air tight joint be-.

tween the sashand the window frame when the sash is closed, I provide the edge of the side stile of the sash upon its outer face with a recess 39 to receive the projectingportion 16 of the side wall of the supplemental stile 13,- and in the base of this'recess a strip of felt, rubber, or other compressible material indicated at 40 is secured. in any preferred manner. This strip ofmaterialwhen the sash is swung to its closed position, engages upon the surface of the projecting'portion 16 of the sliding stile and effectually prevents the flow of air between the fixed window stile and the supplemental stile. The Henge 1-; of the sliding stile serves to prevent the exterior cold air finding its way between said stile and the frame of the window and into the room or apartment.

From the foregoing description taken in connection with. the accompanying drawings, it is believed that the construction and manner of operation of my improved window will be clearly understood.

By the provision of my improved holding device for the supplemental stile whereby the stile is securely held in position in the swin ing movement of the window sash, the sash is at all times maintained in its proper position with relation to the frame when it is opened and closed, and the liability of the sash assuming an angular osition in the frame owin to a greater weight at one side of the sash t ian at the other is entirel overcome. Thus, the sash is prevente from binding at its sides against the frame of the window and the supplemental stiles are also relieved of the pressure of the sash which would result from such an unequal distribution of the weight.

As the device as a whole ,comprisesbut few elements in its construction, it will be obvious that the same can be produced at small cost and easily and quickly installed in position for use.

While I have shown and described the preferred form and arrangement of the various parts, it will be understood that the invention is susceptible ofconsiderablc modiliratlon without departing from the essential features or sacrificing any of the advantages thereof.

Having thus described the invention, I claim:

1. The combination with the window frame and a sash mounted therein for sliding and swinging movement, of a spring pressed locking device arranged adjacent to the pivot of the sash, and means carried by the sash to hold the lockin device in an ineffective position during the sliding movement of the sash, and adapted to release said locking device for frictional engagement with the window frame at any point in the sliding movement of the sash when said sash is swung out of the frame to its 0 )en position to hold said sash against furt ier slidin" movement in either direction.

2. The combination with the window frame and sliding stiles mounted therein, a sash pivotally mounted upon said stiles, of leaf s rings fixed to the sliding stiles and provi ed with holding blocks to frictionally engage the window frame, the free ends of said springs being disposed adjacent to the pivots of the sash, lugs carried by he sash to engage said springs and hold the blocks out of frictional en agement with the window frame during the sliding movement of the sash, said lugs when the sash is swung out of the frame releasing the s rings to permit the blocks carried there y to be forced into frictional engagement with the window frame and hold the stiles against sliding movement in either direction when the sash is in its open Position.

In testimon whereof I hereunto aflix my signature in tie presence of two witnesses.
